WBJEE

If you are a general rank holder, then getting into the above -mentioned streams in any of the known government engineering colleges will be difficult for you, (I think you can try out IT at Jalpaiguri or Kalyani government engineering colleges, you might be fortunate enough in the 3rd round)
Unfortunately, there will be no room for you in JU and IIEST Shibpur with the above-mentioned rank, provided if you are a general category student.
However if you opt to study in non-government engineering colleges, you can get IT in IEM but not CSE, same with Heritage, IT is a guarantee however if you are lucky enough, you can get CSE in perhaps the 3rd or 4th round of counselling in Heritage.
PS: Some guy has mentioned about a WB domicile being required at JU, here I recommend people having no information or less information should not answer and simply pass the question on. Jadavpur University along with some other self financing universities does not demand a WB domicile for admissions.
Good luck to you.:)

The major thing that you should follow is the pattern. Maths is given the highest priority with 100 marks and is considered to be the lengthiest paper. Indeed, it is lengthy but the art of choosing questions play a key role here. One has to choose questions at first that are easy to solve and are scoring, then try for the little tough ones and if there is time, go for the difficult. If you choose questions correctly,60+ in maths can be achieved. Now, physics and chemistry are 50 marks each. For physics I would say chapters of optics, electrostatic, AC and magnetism are very important. One must be good in waves and kinematics and chemistry, it's easy if and only if you have gone through NCERT thoroughly.

Dear Priyam, C

In case you don't get your desired college, don't settle for something mediocre. Instead of settling down for some mediocre college, it would be better if your try for some good private university. Many reputed private universities are offering B.Tech CSE. They have their different criteria for admissions. Some offer admission on basis of JEE scores, some offer admission on basis of their own tests and some offer admission on the basis of both. Some even offer direct admission on basis of class 12 marks.
Some of the universities also offer scholarships on basis of your performance in class 12 or JEE or even during the course. You can check the details of any of the reputed universities like VIT, Lovely, SRM, etc. All these universities have wonderful infrastructure and world-class facilities to offer to students apart from good placements.
